It's not really a good idea to send 3mb+ photos via Hotmail. In addition to filling up your own email box, you'll be filling up other people's email boxes. A few years ago I would have recommended that you compress the photos together using ZIP but nowadays that doesn't save as much space as we would want. It's probably best to join a photo sharing site: like Windows Live SkyDrive, Yahoo Flickr, or Google Picasa. That way you can post entire batches of photos (from kids birthday parties to Christmas morning package destruction) and then people can choose which photos they want to look at -- which is also more polite than dumping a bunch of high-res photos into your friends' and family's email.
